Mirth of a Nation: The Best Contemporary Humor, originally published in 2000, is an anthology of contemporary humor written by over fifty comedians, Writers, and other funny fellows, and edited by Michael J. Rosen. Mirth of a Nation was reviewed positively by January Magazine, a review in which Jonathan Shipley said that “Michael Rosen, author and Editor of many notable books for adults and children as well as the literary Director of The Thurber House, has collected some funny writing. Seriously, it's good stuff.” When interviewed, Michael J. Rosen said that “Mirth... and More Mirth of a Nation make another claim: That humor writing is seriously funny. Now of course I mean "genuinely" funny, but I also mean also "seriously" as in "profound" — humorists are among the few dependable sources of honest (re)calibration and reality checking.” The volume was later published in 2002 as an audiobook, and in 2007 in hardcover format. Rosen also edited two additional humor anthologies in the same vein, More Mirth of a Nation (published November 2002), and May Contain Nuts (published September 2004).
